This Vant Shelf, a modular flatpack shelving system, is by Gothenburg-based furniture designer Hampus Penttinen.

"Vant Shelf is based around the idea of opposite screw threads between which you have threaded connecting rod. By turning this rod, the opposing parts pull tighter, or push apart."

"By utilizing this simple yet ingenious concept in a piece of furniture, only one turning action is needed to complete the assembly. The modules can be stacked or lengthened as needed, resulting i everything between a single low coffee table, via media furniture, to full ceiling height shelving."

Penttinen collaborated with Helsinki-based furniture designer Hemmo Honkonen on this Beak Shelf, which is also modular and flatpack:

"Beak Shelf is a knock-down shelving system for public or private spaces. Beak utilises the flexible properties of beech wood in a disassemble-able joint which is easy and satisfying to use, taking the knockdown experience to a new level. The aprons are simply clicked on to the sides and secured in place with wingnuts."
